357Sig KB w/KKM BBL Underwood Ammo

[The_Shadow]

rogn, they do have a 10mm cartridge that is necked down to the 0.355 or 9mm, its called the 9x25Dillon.  It works well aslo from the 10mm platform of guns with a barrel swap.  Something like a 95 grain pill screaming at 2100 fps, 115 at 1800 fps...

Im embarrassed. Thanks for the info. Sounds like a safer way to get the needed horse pressure for the task. BUT, the little 10 seems to be more pragmatic.

I love the 357 sig.  It shoots so flat, so accurate, and hits with so much velocity.  I like the 9mm bullet because of the yaw, but I don't like the velocity.  I seriously looked for a Glock in that caliber but never could find one in person. 

I don't care what anyone says, increased force plays a part in stopping power.  Yeah a 22 will kill by knocking out a major vessel, but the shearing caused by larger calibers also plays a large part.

I'm thinking reloading dies in the Dillon may be REAL expensive, and so will store bought ammo, which would also be much harder to find than 357 SIG ammo. And just how fast DO you want to push a 9mm pill, anyways, That said I have a 9mm, a 9mm Mak, a .380, like I said... my P229 fires both 357 Sig and 40 cal S&W, and I have two 10mm's. I think I have all the bases covered.

That said, I know NOTHING about Underwood Ammo. Is it supposed to be hot stuff?

The 10mm kills in large part by the explosion factor.

Not supposed.  It is.  No current 10mm ammo maker loads it as hot or hotter than Underwood.

This.

They advertise VERY hot 10mm loads.  And in testing by various forum members, we have found their advertising to be a little off.  They almost always EXCEED the advertised numbers.

Well if velocity was all that important to me, I would have a chrony.

It isn't though, all I want is accuracy. A 10mm 185 grain slug will do enough damage without needing warp speed delivery.

Thing is the 10 and 357 are going pretty close in speed, although the 10 will have more force because of mass.

And the 10mm will usually poke a larger diameter hole on top of it.

And here I thought they made 357 SIG to hit .357 mag velocities.

[REDLINE]

They did, specifically from the standpoint of a 125gr bullet and velocity from a common carry sized platform used by LE.

The .357 Sig was never intended, nor did it achieve, .357M power levels (in comparative commercial loadings).  It was marketing.  .357 Sig just sounds better than .355 Sig, or 9mm Sig.

[gandog56]

Well, since an option for my SIG P229 in .40 cal, was a barrel for 357 SIG, I figured why not, since it uses the same magazines. $140 for a new SIG barrel is a whole lot cheaper than a whole new SIG pistol.

Recieved the ammo from the box that caused the KA-Boom!  See the pull-down info...
